LIGHTING-FIXTURE.

T 0 all whom it mag/ concern Be it known that I, FREDERICK W. WAKE-- FIELD, acitizen of the United States, and a; resident of Vermilion, county of Erie, and State of Ohio, have invented a new and useful Improvement in Lighting-Fixtures, of which the following is a specification, the principle of-the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions. Myinvention relates in general to 'light-' ing fixtures and its general object is the ro-.

vision of an improved canopy to whic a number, of individual lights may be secured, and the invention'will find its chief application in electric fixtures.

To the accomplishment of these and re-.

lated ends said invention thenflconsists of the means hereinafter fully described and particularly pointed out in the claims.

Theannexed drawing and the following i 3 is a section on the line A-A in Fig. 2', Fig.

. 4 is a section on the line B-B in Fig. 2;

Fig. 5 is a section on the line B-B in Fig. 2 with onejof the parts in difi'erent position than in Fig. 4 and showi g a cover plate; Flig. 6 is a perspective v ew of the cover p ate. l

The canopy'may be supported from the wall or ceiling in any convenient manner, but in the drawings there is illustrated a crows-foot 1 which is attached to the ceiling and from which is suspended arod 2 bearing a head 3 at its lower end. The canopy is supported from the rod 2 by a supporting member 4 which enters into the construction of the canopy. Below the sup porting member 4 is a nut 5 bearing a set screw 6 by means of which the member 4 may be secured in any desired position on the rod 2; the nut 5 supports a bracket 7 bearing a nipple 8, and by means of a nut 9 threaded on the nip lo a second canopy 10 is supported below t Specification at Letters Patent. Application filed July 7, 1911. Serial No. 837,244,

- to conceal certain '19 which covers the flang 6 main canopy so as 1parts entering into the construction of the xture.

Patented MarA, 1913.

Themain canopy may be of any desired shape, but of whatever shape it may be, I

propose to make it out of a plurality of similar sections, -Canopies of this sort are usually made of sheet brass or other sheet metal, and it has been usual to make them of one piece of metal. By making them out of a, plurality of similar sections, as in the present invention, a considerable saving of 'material is had, because the difi'erent sections may be stamped .reversely from a' single sheet of metal. Furthermore, after these sections havebeen stamped, they may each be polished separately toward the center so that the finished fixture will be much more elegant in appearance.

The several sections which form the can-"- opy proper are supported from the member 4which is formed with a plurality of ribs 11 and adjacent to each 0 theribs 11 are formed outwardly facing shoulders 12. The I sections 13 of the canopy are formed at their meeting edges with flanges 14 and in assembling-the fixture, the inner edges 15,.of the soctlons 13' are fitted into the shoulders'12. Screws or other retaining means 16 are then utilized to Secure'adJacent flanges 14 together and to secure these flanges to the respective ribs 11. It may be desirable to further tie together. the outer extremities of adjacentsections 13, and for this purpose I employ angles 17 secured to the sec-' tions 13.

In order that individual lamps may 'be supported from the canopy, I provide any desired number of Hi ples which may be conveniently held in t e cano y by a late ed end o the nipple 18, this plate beingsecured to the canopy by screws 20.' These nipples are preferably attached to the canopy on the meeting lines of the sections as clearly shown in Fig. 2, for by this means additional strength is given to the canopy. The nipples 18. are preferably interiorly threaded and when a lamp is to be attached at a given nipple, a coupling 21 is threaded into the nipple 18 and to the lower end of the coupling may be secured a lamp socket. This position of the parts is illustrated in F ig; 4. It is often desirable, however, that more or less lights be secured to a canopy,

and therefore itis at times desirable to conceal nipples which it is not desired to use. In such case the coupling 21 may be threaded into the nipple 18 from the innerside of the canopy and the outer end of the nipple may be concealed by an ornamental plate 22 which is provided at its ends with recesses 23 which may engage under the heads of the screws 20.

From this description of my invention its many detailed advantages should be apparent and as a whole it provides an ornamental fixture which lends itself admirably to' manufacture, and which may be quickly assembled as a fixture having difierent-desired numbers of individual lights. The provision of flanges along the meeting edges of the sections and the securing together of such flanges provides, in effect, a series of radiating ribs or trusses for the canopy structure. As these ribs extend from the central supporting member to the nipples 18, they will be seen to be admirably adapted to take up the bending strain, which the weight of the lamps and their connections impose upon the canopy, unsupported asthe latter is, save at its center. The unsightly deflection of the outer edge of the canopy, leaving a space between it and the ceiling is thus entirely avoided. The advantages just described will still be enjoyed, even though the lamps be suspended at points intermediate between the aforesaid ribs.- This 'may be found desirable, or necessary as for instance where -more lamps are suspended from the canopy than there are ribs to the latter. I Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1. In a lighting fixture, a canopy, comprising. a'central supporting member p'ro vided with a plurality of radially extending ribs, a plurality of similar sheet metal sections, the meeting edges of said sect-ions extending radially from said member and being provided with flanges, means securing together the adjacent flanges, and means securing said flanges to the respective ribs.

2. In a lighting fixture, a canopy, comprising a supporting member provided with a plurality of ribs and with outwardly facing shoulders adjacent said ribs, a plurality of a central supporting member, a plurality of similarsheetmetal sections removably ser 'cured to said member, and a plurality of nipples secured to said sections.

4. In a lighting fixture, the combination of a central supporting member, a plurality 'of similar sheet metal sections removably secured to said member, a' plurality of nipples removably secured to said sections, and removable means for covering unused nip- P t 5. In a lighting fixture, the combination of a supporting member, a plurality of similar sections removably secured to said member, a plurality of nipples removably secured in said sections, plates provided with recesses at their ends and adapted to cover unused nipples, and screws engaging said recesses and threaded into said sections.

6. In a lighting fixture, the combination of a supporting member-provided with a plurality of ribs and with outwardly facing shoulders adjacent said ribs, a plurality of similar sections having their inner edges engaging said shoulders, said sections being provided with flanges at their meeting edges ai'allel tov the respective ribs, means securing together the adjacent flanges, means securing the flanges to the respective ribs, a plurality of nipples remov'ably secured in said sections, plates for covering unused nipples, andmeans for removabl'y securing said plates to said sections.
